I know, with 2x speed the glitch is less important but still there... It only disappeared when i switch to 1x.
But the game is an advanced aga game, for a good result you need a 68030 50 mhz i find strange that i have to slow done to cpu frequency to 1x to have the intro without glitch !
But i must admit that i don't remmeber if it glitches the same way on a real amiga.... I still have the game but my amiga 4000 just crash and burn !!!
I can't make a test anymore on the real thing and my memory isn't good about this bug i don't remember if it was present on my real amiga 4000 or if it comes with winuae.
If someone could test genetic species on a real amiga...If it works well on real amiga it means that something could be improve into winuae.
But 1st it could be cool if someone could test it on a real amiga, if the glitches are there, you can't miss it during the intro, by the way the game run just fine under winuae just too bad that one of the more beautifull amiga intro just glitches like that.

...but I only use AGA (via WinUAE); none of this RTG / graphics card stuff.

Lol...That came across like an old man screwing his face up and saying "ruddy technology, wasn't like this in my day"

but more on topic, I hope people testing stuff bother to check if the program supports certain hardware or it needs to be a basic machine, also slapping JIT on with a 68030 to run Defender of the Crown etc usually causes more problems.

Seen so many reports over the years where there's some horrendous configuration that would struggle on a real Miggy and Toni gets this generic "it don't work" report...

It still gets me that he to this day still has to ask for logs despite it being on every beta thread....Bah...

That's why i asked i didn't know that you just tested it on winuae.
I played it on real amiga at the time but really, i don't remember it had the glitch or not and sadly my a4000 is dead and i can't anymore test it.

your solution is not bad at all but i'll try to make something to make the intro run x1 speed and switching to higher speed after.
Is there a way to make it ???
I'll see... For me it's one of the best cdxl ever at the time never thought that it was a cdxl or forgot about it.
Really good cdxl intro... But was it a special cdxl player or a cutomized one by the coders ??
